I have not seen this plant. In tbe extreme shortness of its 
petiole it approaches the preceding species ; the leaves are some- 
what dififerent in form ; and in the peculiar character of its 
inflorescence it is at variance with all others of this section. 
The plant is only 18 inches high, and is found growing in grassy 
plains in the upland districts of one of the southern provinces of 
Brazil ; its leaves are about ^ inch apart, and erect ; in the 
they are 1-1 1 inch long, f-lj inch broad, on a petiole 2 lines 
long : in the ? they are 2-3 inches long, 1-1^ inch broad, on a 
petiole of 2 lines. The ^ raceme is about 1^ inch long, with 
three or four alternate axils, each with an acute obovate 
bract, 4 lines long, 2 lines broad, and an almost sessile and 
nearly capitate head of flowers of the same length ; the ? raceme 
is only ^ inch long, imbricately crowded with rufescent bracts, 
3 lines long, 1 line broad, and each concealing a fascicle of six 
minute flowers, on pedicels ^ line long, the sepal being I line 
in length.
